• If the standard solution concentration is validated,

will appear on the LCD. Press to update

calibration. The calibration point value will be added to the Calibrated Standards section.

• The “Please wait...” message will appear on the LCD until the reading is stable and 10 seconds elapsed,

time in which immerse the Ion Selective Electrode and the temperature probe into the next standard solution

and follow the above procedure or press to exit calibration.

Notes: • The new added calibration point will replace an old

one if the difference between them is less than 20%

of the standard solution.

• If the existing stored calibration is full (five calibra-

tion points), a pop-up menu will be displayed on the

LCD in which you can select with or

the standard solution you want to replace with the

current one. Press to delete the selected

calibrated point and then press to update

calibration with the new standard solution.

• If the isopotential point of the electrode is unknown, the

ion calibration and measurements can be performed only

without temperature compensation (see ISE Setup, Tem-

perature option for details, page 33). When the temperature

compensation option is disabled, at least a two-point

calibration must be performed in order to perform ISE

measurements. Otherwise, “-----” will appear on the LCD.

• When in MTC mode, if pressing after enter-

ing ISE calibration and while a standard solution is

selected, a pop-up menu will be displayed on the LCD

in which the concentration and the temperature value

can be ajusted by pressing and then

or keys. Press to save the modi-

fied value and then / to select

next /previous value to be adjusted.

CALIBRATION MESSAGES

• Wrong standard solution. Please check the standard solution: this message appears when the
